"blown speakers"

When a speaker "blows" what actually happens. I suppose its different between a tweeter and woofer, but is there some mechanical damage or is it electrical. does something break? Besides a woofer cone ripping, what happens to a tweeter if it is still working, but raspy or staticy? I have heard "blown" speakers before, or ones that didnt work at all, but I really dont know what it is that breaks and whether it is fixable or just replace.

If you can move the driver over to the other speaker; pay attention to which wire goes to the proper terminal of the driver to see if the problem moves;if it moves then you have identified the driver as being bad.
If these are a expensive or special driver and is damaged I would talk with Bill Legall of Millersound to get his opinion;he is highly respected in the business and his work is of the highest caliber.

I would have to agree it maybe a crossover failure as well;any chance it is fuse protected,do you have the crossover out or viewable?

You could take a driver out 1 at a time and using a DVM measure the resistance of the speaker at the speakers terminals;maybe one is open and if they are wired in series then all the drivers would appear to be non operational.
